Find the side of a right triangle
lisabon 2012 [21]

The 2 sides of the right triangle is 25 and 24.

Any multiple of a Pythagorean triple is also considered a Pythagorean triple. Multiplying 3, 4, 5 by 2 gives 6, 8, 10, which is another triple. To see if a set of numbers makes a Pythagorean triple, plug them into the Pythagorean Theorem.

3,4,5     5,12,13     7,24,25    8,15,17     9,12,15

Final Result: 25,24

Find the point P on the parabola y=x^2 closest to the point (3,0).
lutik1710 [3]
<span>if we take square root (x - 3)^2 + y^2
y = x^2
(x - 3)^2 + x^4
f(x) = x^4 + x^2 - 6x + 9.
first derivation:
f'(x) = 4x^3 + 2x - 6.
4x^3 + 2x - 6 = 0.
one solution is x = 1
second derivation
f"(x) = 12x^2 + 2
it is positive for x = 1
hope it helps

Trevor’s total employment compensation is $33,500. If Trevor has no job expenses and his gross pay is $28,600, then his total em
EleoNora [17]

we know that

Total\  employment\  compensation=gross\  pay+employee\  benefits-job\  expenses

in this problem

Total\  employment\  compensation=33,500\ dollars

gross\  pay=28,600\ dollars

job\  expenses=0

Step 1

Find the total employee benefits

Let

EC------> total employment compensation

EB--------> total employee benefits

GP------> gross pay

JE------> job expenses

EC=GP+EB-JE

33,500=28,600+EB-0\\ EB=33,500-28,600\\ EB=4,900\ dollars

Step 2

Find the percentage of the total employee benefits

we know that

total employee benefits is equal to 4,900\ dollars

gross pay is equal to 28,600\ dollars

by proportion

\frac{28,600}{4,900} =\frac{100}{x} \\ \\ x*28,600=100*4,900\\ \\ x=\frac{100*4,900}{28,600}

x=17.1%

therefore

the answer is the option

d. 17.1
